Is there a way to prevent IE10 / IE11 from showing open or saved tooltip
I am uploading files from server using javascript blob, something like
let blob = new Blob([resposne['_body']], { type: contentType });
if (navigator.msSaveBlob) {
navigator.msSaveOrOpenBlob(blob, fileName); // in case of IE
} else {
let objectUrl = window.URL.createObjectURL(blob);
window.open(objectUrl);
}
The code above works fine, but in IE it shows a dialog:
Also, if I put the direct pdf link in the href tag, then it works fine too. So it looks like there is no problem with the adobe plugin.
I just want to open the file and not show this prompt. I tried a registry hack as suggested here , but no luck. Any ideas how to do this?

For those who are facing the same problem, I solved it using window.open
. Instead of downloading the response, I directly pass the url window.open
to something like
window.open(apiUrl) // Exmp "host:api/documents/download?id=1"
Note: -API must return a stream response with the header type set. In my case, the C # web API method was
public HttpResponseMessage Download(int id)
{
var data = _service.Download(id);
HttpResponseMessage result = null;
result = Request.CreateResponse(HttpStatusCode.OK);
result.Content = new ByteArrayContent(data);//here data is byte[]
var name = data.Name.ToLower().Contains(data.DocType.ToLower())
? data.Name
: $"{data.Name}{data.DocType}";
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("inline")
{
FileName = name
};
result.Content.Headers.ContentType = new MediaTypeHeaderValue(MimeMapping.GetMimeMapping(name));
//here i am setting up the headers content type for example 'text/application-json'
return result;
}
Hope this helps someone.
